WINDOW SCREEN OB SASH HANGER.

Application filed May 20, 1912.

To all whom it may cmwern:

Be it known that I, PETER FRANTZ, a citizen of the United States of America, and resident of Sterling, Whiteside county, Illinois, have invented a certain new and useful Improvement in Window Screen or Sash Hangers, of which the following is a specification.

My invention relates to window screen or sash hangers of that kind in which each hanger consists of one part which is secured to the window frame and another part which is secured to the screen or sash, the two parts removably or detachably engaging each other, and the construction being such that the two parts serve as a hinge for permitting the lower end of the screen or sash to be swung outward.

Generally stated, the object of my invention is to provide a highly efficient and novel construction of window screen or sash hanger of the foregoing general character.

Special objects are to provide a hanger of such novel form and construction that both parts thereof can be manufactured from sheet metal with a minimum of waste; to provide a novel form of hanger of this kind in which the construction is such that the screen or sash can shrink or become displaced laterally without causing the hanger parts to cramp or bind; to provide a novel form of hanger of this character in which the formation of the parts thereof is such that each part can be stamped out of sheet metal with economy of labor and time; and to provide certain details of construction tending to increase the general efficiency of a window screen or sash hanger of this particular character.

To the foregoing and other useful ends, my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawingsFigure 1 is a front elevation of one of the upper corner portions of a window frame and sash, showing a hanger applied thereto, embodying the principles of my invention. Fig. 2 is a horizontal section on line 22 in Fig. 1. v Fig. 3 is a side elevation of that part of the hanger which is secured to the window frame. Fig. 4c shows a flat strip of sheet metal in full lines, and illustrates in dotted lines the manner in which one part of the hanger is stamped or otherwise cut out from the body of sheet metal, and showing how Specification of Letters Patent.

one blank fits into the other to economize material and reduce waste. Fig. 5 shows one of the blanks of Fig. l'detached from the body of sheet metal. Fig. 6 shows a strip of sheet metal in full lines and illustrates in dotted lines the manner in which the other part of the hanger is made from sheet metal, showing the manner in which one blank fits within the other to economize material and reduce waste. Fig. 7 shows one of the blanks of Fig. 6 cut out or detached from the body of sheet metal.

As thus illustrated, and referring to Figs. 1, 2 and 3, it will be seen that the hanger characterized by my invention comprises a frame member A which is secured to the face or outer surface of the window frame, and a sash member C which is secured to the face or outer surface of the sash or screen. The frame member A comprises a flat body portion a provided at its upper end with a lug a and a notch A Referring to Figs. 2 and 3 it will be seen that the lug a is turned outward at an angle to the flat body portion of the member A, and that it has an upturned prong or retaining portion a whereby a notch or recess a is provided at the top of the member. This member A is preferably secured in place by upper and lower-screws a and a inserted through holes in the sheet metal.

The sash member C comprises a fiat body portion 0 provided at its outer end with two prongs 0 having a notch 0 between them, and provided at its inner end with an ear 0 the said body portion 0 and the said ear 0 resting fiatwise against the surface of the sash or screen and being secured thereto by outer and inner screws 0* and 0" inserted through holes formed in the sheet metal. By referring to Fig. 2 it will be seen that the prongs 0 are outwardly displaced from the vertical plane of the body portion a, whereby these prongs embrace the lug a and rest fiatwise against, the outer surface of the member A, whereby the two members overlap. WVith this arrangement it will be seen that the prongs 0 extend laterally from the side edges of the sashor screen, the inner edge of the member A being preferably close to the inner edge of the window frame. The sash or screen is manipulated horizontally to bring the upper prongs 0 at opposite sides of the sash or screen, into the notches a and the lower end of the sash or screen 110 is then swung downward and into the win dow, causing the lower prongs to move downward and assume positions below the lugs (6 as shown in Fig. 1, whereby the sash or screen can shrink or become displaced laterally, to some extent, without causing the hangers to cramp or bind, as the said notches are of some depth.

Then the sash or screen is closed, the hangers are in such condition that both parts tightly hug the outer surface of the window frame and sash, the notches a being of-such shape or form, it will be seen, that the body portions of the members A and C are in the same vertical plane when the sash or screen settles into place and is closed.

A further advantage and utility of the special formation and construction shown for the member A is as follows: In the manufacture of these parts a strip of sheet metal is provided, as shown in Fig. 4, and the blanks for the members A are stamped or cut therefrom in the manner illustrated in dotted lines in this figure. Thus it will be seen that the lug and prong a and a of each memberare adapted to fit within and form the notch A of the next or adjacent member, whereby there is practically a minimum of waste, the material punched out for the screw holes, and also the small portions (6 which are punched out to form the notches a, being practically theonly material lost or wasted in the manufacture of these blanks.

A similar advantage and utility relative to the particular formation of the member C is as follows: In the manufacture of these parts a strip of sheet metal'is provided, as shown in Fig. 6, and the blanks for these members are stamped or cut therefrom in the manner shown in dotted lines. Thus, it will be seen that each ear 0" of one member fits within and forms the notch c of the next or adjacent member. WVith this method the material punched out for the screw holes constitutes practically the only waste or loss, the attaching portion of one blank being punched or cut out to form the mouth or notch of the next or adjacent blank. In this way, and with the hanger characterized by my invention, the cost of manufacture is practically reduced to a minimum, and at the same time the hanger is rendered more satisfactory in use. It is easily attached to the window frame and sash or screen, and by reason of the open notch or mouth provided at the outer end of each sash memmembers, it is comparatively easy to adjustthe sash or screen in place, and to remove the same when necessary. Moreover, and

7 by reason of the wide notch 0 the two parts of the hanger need not be exactly at right angles to each other. In other words, the parts need not be accurately fitted or applied, because the hanger will operate even I dow.

If desired, the frame member A can be used in a flat condition, as shown in Fig. 5, by mortising the said member in the window framethat is, by applying it in this manner to the inner surface of the window frame. I

Thus, there areseveral advantages which result from the use of the rounded notch c as distinguished from a mere vertical slot.

For example, this notch permits the plate C to rotate on the base of the lug on the other plate, about an axis passing through the said lug at right angles, or substantially at right angles, to the plane of the sash or screen. In otherwords, the plate C could be skewed about the said axis to quite an extent (see Fig. 1), so that it would not be square with the sash or screen, and still not affect its operative engagement with the lug on the other plate. On the other hand, the plate A could be skewed about said axis from the position shown in Fig. 1, and still the two plates would operatively engage each other when thesash or screen is brought into position. The precise and accurate adjustment or positlonlng of the two plates, which was heretofore necessary with devices of this kind, is not important or imperative in the application of my invention to practical use. Furthermore, the use of the rounded notch c not only obviates the necessity of accurate relative positioning of the two plates, but also permits the metal which is cut away from this notch to be used as the attaching portion of another plate. Thus, the rounded 1.

notch c is, as stated, much better than a straight slot, as it not only facilitates the use of the invention, but also reduces the cost of manufacture thereof. With thisv rounded notch, each plate can be rotated while in engagement with the other, or relative to the other, and each plate may, therefore, be said to have a plurality of efiective positions relative to the other, as each plate is operative when moved to any one of several positions within the range of variation afforded by thelrounded notch and the conditions in genera What I claim asmyinvention is:

1. In hangers for sashes or screens, a stationary sheet-metal bracket-plate formed with an up-turned lug extending outward from the plane of the sash or screen, and a movable sheet-metal plate for attachment to the sash or screen, said movable plate having a notch in one end thereof to receive said lug, said notch being shaped to permit variable positioning of either plate relative to the other about an axis passing through the base of said lug at right angles to said plane, whereby each plate has a plurality of effective positions relative to the other.

2. In hangers for sashes or screens, a stationary sheet-metal bracket-plate formed with an up-turned lug extending outward from the plane of the sash or screen, and a movable sheet-metal plate for attachment to the sash or screen, said movable plate having a notch in one end thereof to receive said lug, said notch being shaped to permit variable positioning of either plate relative to the other about an axis passing through the base of said lug at right angles to said plane, whereby each plate has a plurality of effective positions relative to the other, and the two plateshaving their body portions disposed in the same plane, the notched portion of the movable plate resting fiatwise against the bracket-plate body.

3. In hangers for sashes or screens, a stationary sheet-metal bracket-plate formed with an up-turned lug extending outward from the plane of the sash or screen, and a movable sheet-metal plate for attachment to the sash or screen, said movable plate having a notch in one end thereof to receive said lug, said notch being shaped to permit variable positioning of either plate relative to the other about an axis passing through the base of said lug at right angles to said plane, whereby each plate has a plurality of elfective positions relative to the other, and the other end of said movable plate having an attaching portion of the same shape as said notch.
